MUSIC-DESK FOR PIANOS.

SPECIFICATION forming part of Letters Patent No. 326,542, datedSeptember 22,1885.

Application filed March 9, 1885.

- York and State of New York, have invented a new and Improved DeskAttachment for Pianos, of which the following specification is a full,clear, and exact description.

This invention relates to a music-desk for supporting the music-leavesof a piano'forte. This desk is intended more especially to be applied toupright piano-fortes and parlororgans, and is so constructed that whenpushed back it is concealed beneath the cover and locks the latter inplace.

The invention consists in the elements of improvement hereinafter morefully pointed out.

In the accompanying drawings, Figure 1 represents a perspective view ofan upright piano embodying my invention. Fig. 2 is a partial bottom Viewof the top plate, showing the forward section swung up. Fig. 3 is avertical transverse section through one of the guide-rails. Figs. 4 and5 are detail views of two forms of the guide-studs; and Fig. 6 is adetail perspective view of the connection between top plate and desk.

The letters I) I) represent, respectively, the rear and front section ofthe top plate of an upright piano-forte, A. The rear section, b, ispermanently attached to the piano, while the front section, b, is hingedto rear section, b, so that it may be opened or closed.

To the bottom of the rear section, I), there are attached two groovedparallel guide-rails, D, and to the bottom of the front section, b, areattached two similar rails, I). These rails D D are in line with eachother,and when the front section, b, is let down they form twocontinuous ways extending from the front to the rear of the entire topplate.

0 is the desk,made of square or other shape, and provided at its rearend with two laterally-projecting studs, E E, which engage and areadapted to slide within the grooved guiderails D D. n

WVhen the desk 0 is pushed back, it passes with its rear end through aslot of an upright partition, J, and thence enters a low chamber,

(No model.)

N, formed beneath the back plate, I). In this position the desk isconcealed beneath the top plate and prevents the front section, b, frombeing opened.

\Vhen the desk G is pulled out, it assumes the position shown in Fig.1that is to say, it projects forward and downward and rests upon theinclined front of the piano. G is a molding or bead secured to the frontsection, b, to the right and left of desk (J. extends in front of theends of rails D D, and serves as a stop for preventing the studs E frombeing bodily drawn out of their guidegrooves.

To the forward edge of the desk 0, I prefer to secure a head, 0,corresponding in shape to head G. Then the desk is pushed back the head0 will connect the two sections of bead G, and thus form one continuousbead from the right to the left edge of the piano.

If desired, the studs E may be made of the form shown in Fig. 5. In thisfigure they are shown to be able to slide in circular channels, in whichthey are held by means of a pin extending through a slot. A coiledspring is placed back of the stud. By pushing the stud E inward the desk0 is detached from the top plate, I) b.

I claim as my invention 1. The combination of piano-forte A, havingsectional top plate, I) b, with rails D D, desk C,having studs E, andwith head or stop G, substantially as specified.

2. The combination of piano-forte A, having sectional top plate, b I),with rails D D, desk 0, having studs E, and with slotted partition J,all being so constructed that when desk 0 is pushed back the cover I) bis locked down, substantially as specified.

3. The combination of piano-forte A, having sectional top plate, I) b,with rails D D, desk 0, having studs E, and molding c, and with moldingG and partition J, substantially as shown and described.
